Abstract:

Over the past decade, microseismic monitoring has become the
most widely used approach to understand of in-situ reservoir behavior during
hydraulic fracture stimulations. From early monitoring performed in the Barnett
Shale to current programs in the Horn River and Marcellus formations, we review
the evolution of microseismic monitoring from the viewpoint of data collection
(single versus multi-well array configurations, use of long lateral stimulation
wells), data analysis and the incorporation of microseismic parameters to
constrain and validate reservoir models.

We conclude with a look at multi-array microseismic results from hydraulic
fracture stimulations of various North American shale plays to illustrate how
microseismic analysis has aided in the understanding of reservoir characteristics
and in turn, helped to plan more effective stimulation programs.  We
highlight case studies where microseismic monitoring was used to help assess
fracture dimensions, stage spacing and well spacing.  In addition, we look
at how the use of advanced analysis techniques such as seismic moment tensor
inversion (SMTI) has helped propel the industry forward and allowed operators
to gain a better estimate of the stimulated reservoir volume, the discrete
fracture network and the effective fluid flow by understanding details on
individual rupture mechanisms and how these mechanisms change depending on
treatment program, local stresses and local geology.
